In this paper the impact of basicity on the green ball quality and cruslring strength of pellets had been investigated by changing the ratio of A fine powder and B mineral powder. When the basicity is increased, the incidence strength and the compression strength of the green ball gradually decrease, but thermal explosion temperature increases. At the same time hematite crystal grains develops and grows up continuously in the process of roasting,however, the low melting point silicate minerals producing in the pellets increases in volume and aggregate together, which will worsen the connection degree of hematite crystal, at the same time, the ratio of pore in pellets increases, causing the decrease in compressive strength of pelletsgradually.
